Hybrid rocket engines

I have designed, built and tested a number of hybrid rocket engines systems, for a variety of applications. Hybrid rockets burn a solid fuel with a liquid oxidiser; hence hybrid because it is like a cross between traditional solid propellant motors and bi-liquid engines. In the course of this work I have used typical hybrid fuels, plastics, rubber, wax, and some more unusual ones; in conjuction with liquid and gaseous oxygen and nitrous oxide.
I have also contributed to, and assisted in, the development of hydrogen peroxide monopropellant and LOX/Kerosene bi-liquid propulsion systems. I am always interested in aiding or providing the construction of new systems and can respond to requirements very quickly.
